UNITED STATES CHRISTOPHEE CARTER ANDERSEN. OF SALT LAKE CITY, UTAH.

ELECTRIC STARTER.

Application filed May 3,

To all 10 hem it may concern Be it known that I, CHRIsrorHnn C.ANDnnsnN, a citizen of the United States, residing at Salt Lake City, inthe county of Salt Lake and State of Utah, have invented a new anduseful Electric Starter, of which the following is specification.

This invention has reference to electrically controlled starting devicesto be employed in connection with internal combustion engines forimparting the initial movement to the engine.

The primary object of the invention is to provide novel means, wherebythe starting pinion may be manually moved into mesh with the teeth ofthe fly wheel of the motor, while the pinion is in an inactive position.

Another object of the invention is to provide means for simultaneouslycompleting circuit to the motor controlling the operation of the pinion,when the teeth of the pinion are properly meshed with the teeth of thefly wheel.

A still further object of the invention is to provide means for manuallycontrolling the electric circuit to the starting motor.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is an elevational view of a starter constructed in accordancewith the present invention and disclosing the pinion thereof in meshwith the teeth of a fly wheel of an internal combustion engine.

Figure 2 is an elevational view disclosing the starting pinion in itsinactive position.

Referring to the drawings in detail,.the reference character 5designates the fly wheel of an internal combustion engine, the

same being provided with peripheral teeth 6 to be engaged by the teethof the starting pinion 7 in a manner to be hereinafter more fullydescribed.

The reference character 8 designates a supporting arm which is disposedadjacent to the fly wheel 5 and is formed with a pivot 9 for pivotallysupporting the starting 1922. Serial No. 558,259.

motor 10. which is shown as provided with a flange 11 formed with anopening to accommodate the pivot 9 for pivot-ally supporti g the motor.

Associated with the supporting arm 8 is a bracket 12 which may form apart of t e support ng frame oi the internal comtion en ine, the bracket12 being formed with an opening to accommodate the bolt 13 which isinsulated fron'i the bracket 12 as by means of the insulating material1-1. This bolt 13 is provided with a head 15 at one and th 2 f. theopposite end supporting the sed nuts 16. between which the terminal 1':or the electric wire 18 is held.

The wire 18 has connection with the switch member 19. which in turn isin circuit with the battery 20 through the wire 21. it. suitablemanually operated switch. 22'is interposed between the wires 18. and 21,whereby the circuit through the wires 18 and 21 may be controlled at thewill of the operator.

The wire provides the circuit between the battery 20 and the arm 8,suitable means not shown being provided for establishing communicationbetween the motor 10 and aria 8, whereby the coils of the motor may beenergized when the circuit is completed therethrough.

Disposed adjacent to the motor is an arm 24 which is formed with acurved extremity designed to engage one wall of the motor and form arest for the motor to restrict movement thereof when the motor is in itsinactive position or out of use.

An apertured ear 25 is formed on the motor casing 10, which aperturedear accommodates one end of the coiled spring 26 which has its oppositeend anchored in any suitable manner to cause the spring 26 to be putunder tension when the motor has been moved to bring the teeth of thepinion 7 into mesh with the teeth 6 of the fly wheel 5 Thus it will beseen that as the pressure employed for moving the motor 10 to its activepostion. is relieved, the reaction of the spring 26 will act to returnthe motor to its normal or inactive position where the same is heldagainst the arm 24.

A contact member 27 is formed on the motor casing and is located withsuch rela tion to the member 15 that when the motor is manually moved toits active position, the contact member 27 will engage member 15completing the circuit to the coils of the motor and causing therotation of the starting pinion 7 for imparting the initial move ment tothe internal combustion engine associated therewith.

Formed adjacent to the face of the motor, is an ear 28, to which theoperating rod 22) is connected, the operating rod 29 having a pedal notshown, at the outer or free end thereof, whereby the operator may byexerting a pressure on the pedal move the motor 10 to its activepostionn In order that the contact between the iember 27 and member 15will be insured, a coiled spring 30 is provided on the bolt 13, whichspring member is energized so that when the'memher 27 engages therewith,the spring will complete the circuit to the motor, prior to theengagement oi" the members 15 and 27.

In the use of the device, the switch mem ber 22 is moved to complete acircuit through the wires 18 and 21. \Vith the circuit completed at thispoint, the rod 99 is moved to bring the starting pinion 7 into propermesh with the teeth 6 of the fly wheel 5.

After the teeth of the pinion 7 have been moved to mesh with the teethof the fly wheel 5, the circuit is completed to the motor, to the endthat the pinion 7 is revolved, imparting the necessary rotalv movementto the fly wheel 5 for starting the internal combustion engine ot whichthe fly 'wl eel is a part.

Having thus described the invention, what is claimed new is Incombination with the toothed tly wheel of an internal combustion engine,a starting device including a motor, having a shaft, a pinion. supportedthe shaft to move therewit means for moving the motor and its c to causethe pinion to mesh with the teeth ot the fly wheel, a cont-act membercarried by the motor, a statio m Contact memher lying in the path oftravel of the motor when the motor is being moved to its active osition,a coiled spring secured to the s :1- tionarv contact member 1ndextending "rein to contact with the contact meniher carried by themotor, and complete the circuit l e motor to cause the operation oi themotor, and means for automatically returning the motor to its inactiveposition.

In testimony that claim the foregoing as my own, I have hereto aliixedmy signature in the resence cit iJWOWltHQSSCS.
